Description
Technical field
The present invention relates to a kind of door closer (door closer) that is used for being installed in snugly the moulding doorframe of door leaf or door leaf, this door closer is equipped with a slide rail connecting rod and a slide rail simultaneously, and wherein slide rail is embedded in the groove at a doorframe.
Door closer has a driving shaft, and this driving shaft comprises that one has the cam disc of two cam working faces.Cam disc is opened piston in a side and and effectively is connected, and connects one to the spring assembly of the closing direction effect of steerable axle and opposite side effectively is connected with a damper piston in the opposed side of cam disc opening on the piston.
Background technology
Known a kind of such in order to be installed on the door closer in door leaf or the doorframe, it comprises gear teeth, in a rack piston with a closing axle co-operating.The very big shortcoming of one such door closer is that because the tooth bar that adopts, door closer combines with the leverage of both arms and only has the moment of opening of gradually falling.The door closer of this pattern, it is equipped with a rack piston and is equipped with a slide rail and a control arm, has operation comfort beyond affordability for the user.This is, slide rail produce in via the co-operating of the control arm and the gear teeth one inept raise greatly open moment.This is opened moment and raises continuously.Therefore this needs the power that raises continuously for the user when opening.In addition, such door closer can not be processed so narrow, and it can be fit in all general thickness gate.
Learn a upper end door closer by DE 33 45 004, it is not to be used for being installed on snugly door leaf or doorframe and to be provided with, but is connected in a slide rail yet.This upper end door closer has one can be in the control arm of swinging that effective damper piston that is connected and is connected with closing axle with one with it to the closing axle that closing direction is handled by a spring assembly.This control arm via the thrust slide supporting that is provided with at its free end in a guide rail.In order to improve such guide rail and the operation comfort that embeds the upper end door closer in the guide rail that only has always; Closing axle has a cam disc; The cam working face of opening direction that belongs to door leaf of this cam disc is loaded by a spring support, and its cam working face that belongs to the closing direction of door leaf is loaded by a damper piston.One such upper end door closer also is not suitable for being installed in door leaf or the doorframe.
Summary of the invention
The objective of the invention is to, a kind of door closer is provided, it is fit to be installed in snugly in door leaf or the doorframe, door that this door closer not only can be used for closing from the right but also the door that can be used for closing from the left side and give the user with acceptable operation comfort simultaneously.One such door closer must be suitable for door leaf or the moulding doorframe of whole universal types and should have a little back axial size and a good efficiency.
This object of the invention reaches through the characteristic of claim 1.Other form of implementation of each dependent claims explanation the present invention conception.
In order to can be used for whole mounting meanss, that is be used for from the right and the door that closes from the left side, door closer has cam disc, this cam disc constitute make door closer also have one gradually fall open moment.Cam disc is provided with two cam working faces, and they have the profile of symmetry.The profile of such cam working face is made up of some different radiuses, and they are close to each other and connect the last profile that forms cam working face.
Can will close the just same so raising of square in zero-bit through such cam working face; Make door also can overcome the resistance of locking bit pin or similar component easily; But can not close in addition yet, in such door, incur danger with causes users with high speed like this.
Because known system is with the interior gear teeth operation of a pinion and a piston, combining with a slide rail produces the gradually high moment of opening, and the people of use must apply this and open moment.Avoided this situation through the application of cam disc; Because the special structure through cam working face influences moment variations; Become the torque that descends rapidly in a higher torque and the process that continues to open and for example make to exist, although a linear spring force that raises in fact occurs at door in zero-bit.
Such door closer preferably has the groups of springs be made up of two stage clips as force-storing device, and they are pieced together into setting each other.This each stage clip is arranged to make the spring force that can only change a spring by means of a spring force adjusting device.Because varying in size of two springs, the spring force of the spring of outside are significantly greater than the spring force that embeds spring wherein.Therefore the spring force that only is used as the spring of outside is conditioned.
One opens piston and spring co-operating, opens piston and constitutes the spring support that is used for two springs.In opening piston via supporting one roller, this roller cam disc that reclines.Because the work plane of cam disc with two symmetries, so this two cam working face constitutes from a common pinnacle, and end in the groove, the roller of in this groove, opening piston is adjacent to cam disc.
At the opposed side of cam disc that is another roller that on the pinnacle, reclines, this roller is equally via a supporting.This roller bearing is in a damper piston.In damper piston, be provided with a spring, this spring is bearing on the one hand on the locking screw and is bearing on the other hand on the valve.In lock-screw, also be provided with a valve gear, this valve gear has a control head.This control valve produces the end stops function of inner door closer.Through such control valve that depends on piston stroke, hydraulic medium can flow away via a passage.Be provided with an excess pressure valve in addition, it can make oil through the channel flow in the damper piston when opening.
Because door closer of the present invention is designed to be installed in door or the moulding doorframe and does not have big size, will be understood that, in door closer, does not also have the buffer medium of a large amount of needs.Therefore for above-mentioned reasons, damper piston be provided with one around seal.
Also produce the very short back axial size of a pair of such door closer through above-mentioned setting.This means again, and such door closer has a desirable moment variations when opening and closing door.
The driving shaft of door closer of the present invention is bearing in the housing of door closer by means of a bearing.Door closer only has an axle output, and this output connects and composes through a corresponding screw and is the bearing of journals, and this bearing of journals comprises a bearing equally.
Because spring-loaded is being opened on the piston when length of spring compressed, reverses so produce one.Open the tendency that therefore piston has the twist motion of participating in this spring.But this means the efficient that reduces door closer, because possibly cause opening blocking of piston thus.For fear of this situation, door closer has a safety lock according to the present invention, and it suppresses to open reversing of piston at least.Improve the efficient of door closer through this measure.Can have kinds of schemes selective, wherein as first scheme spring with open between the piston in the middle of is connected a bearing and is preferably roller bearing, or two-piston (open piston and cushion piston) is connected to each other, thereby directly suppresses the twist motion of two-piston.This for example reaches like this, promptly in piston, adopts safety pin, and this safety pin is being arranged on groove internal support on the driving shaft on driving shaft.
For such inside door closer can be installed, this inside door closer has a fastening devices.By means of this fastening devices, it preferably constitutes the member on plane and is configured to longlyer than door closer, can such door closer be packed in the groove, and this groove is arranged in door or the moulding doorframe.In fastening devices except that each corresponding hole in order in the groove that door closer is fixed on door leaf; The port that also has other; That is one side is used for the output of driving shaft; Be used to lead to each valve in addition, each valve can regulate so that the appropriate use of such door closer, and for example is used to make a weight adaptation in door closer.In addition, in fastening devices, be provided with a regulating sleeve, it is via a transmission device and the co-operating of spring force adjusting device, even so that under the state of packing into of door closer, also can carry out the change of elastic force thus.
Control arm is installed in the end of a driving shaft in the outside.One such motion arm constitutes the straight member on plane, and the protrusion corner angle or the thickening part that have no.Therefore such member must be very thin and narrow, is very little because supply the space of domination at the Men Zhongke with a groove.In order in the door that closes, also to reach essential compressing, this control arm has one and confirms the leading skew of angle, thereby so that gives the essential power that compresses and overcome alignment pin thus.
